Hot metal desulphurisation

Hot metal desulphurisation The hot metal produced with blast furnaces contains relatively high amounts of sulphur, which is detrimental for the mechanical properties of steel. Owing to the limited desulphurisation capacity of converter processes, it is commonplace to conduct hot metal desulphurisation in a ladle or a torpedo car before further treatment at the meltshop. The desulphurisation reagent is typically injected through a submedged top lance.
